class WIDGET_TEST_SET

(source code)

int sum = widgets.stream().filter(w -> w.getColor() == RED)
                           .mapToInt(w -> w.getWeight())
                           .sum();

This example has now become a test set for the EL_CHAIN [G] class.

	description: "[
		An experiment to show how it might be possible to achieve Java-like stream functionality in Eiffel
		by reproducing the following example:
		
			int sum = widgets.stream().filter(w -> w.getColor() == RED)
												.mapToInt(w -> w.getWeight())
												.sum();
	                      
			See: [https://docs.oracle.com/javase/8/docs/api/java/util/stream/Stream.html java/util/stream/Stream]
	       
			This example has now become a test set for the ${EL_CHAIN [G]} class.
